This patch introduces a new ioctl for vhost-vdpa device that can report the iova range by the device. For device that depends on platform IOMMU, we fetch the iova range via DOMAIN_ATTR_GEOMETRY. For devices that has its own DMA translation unit, we fetch it directly from vDPA bus operation. Signed-off-by: Jason Wang <jasowang at redhat.com> --- drivers/vhost/vdpa.c | 27
